Sort of, but not really.

All Allison TES 295 approved fluids are synthetic based which offer improved viscosity that other fluids canít offer.
Synthetic-based is not the same as "fully" synthetic. And even if it were, "synthetic" as used in the US only means "substantially changed" and is not a real standard for anything.

Torque Drive isn't even certified 'fully spec' by Allison is it? Supposedly just 'similar to TES295'?
Correct, it costs time and money to be certified TES 295 (r).

Typically, to meet a proprietary certification, the certifying body lists all the requirements you have to meet.

Engineers go about creating and testing something that will meet the standards, then the company pays a money to the certifying body, who will also test the product and certify it if it passes.

However, if you want to save some time and money, the company can skip the last part and sell their product as "similar to". This product might still meet or exceed the certification standard, even if not certified.

Whether the product is as good as the company says, you either have to trust them (or not) because they are not certified for that application.

Can't say that their product meets (or exceeds) whatever the certification is because then you get "cease and desist" orders

But both Amsoil, UOAs, and the internet have been around for a while now. How many complaints about Amsoil have you seen?
